What problem does this address?

Currently, to enable the AI Experiments you need to check the Enable Experiments checkbox and click the Save Changes button. This means it takes four actions to actually enable a functional experiment.

What is your proposed solution?

Let's update the UI on that settings screen to change the Enable Experiments checkbox to be a button that saves and enables experiments. On refresh the button should change to a Disable Experiments secondary button (with the Save Changes button at the bottom of the page retaining primary button styling). This will mean it takes three actions to actually enable a functional experiment (I know not a major improvement, but still better).

Alternatively, selecting the Enable Experiments checkbox could enable the various Available Experiments settings below.
